Abstract

The invention relates to a wheel bearing for vehicle axles, in particular of a commercial vehicle or a land vehicle, comprising an axle body (2), a hub assembly (4), which is arranged at the axle body (2), a fastening element (6) to fix the hub assembly (4) to the axle body (2), and an intermediate element (8), wherein the intermediate element (8) is arranged untwistably at the axle body (2) and provided between the fastening element (6) and the hub assembly (4).

Claims

1. A wheel bearing for vehicle axles, in particular of a commercial vehicle or a land vehicle, comprising:

an axle body;

a hub assembly, which is arranged at the axle body;

a fastening element to fix the hub assembly to the axle body; and

an intermediate element;

wherein the intermediate element is arranged untwistably at the axle body and provided between the fastening element and the hub assembly.

2. The wheel bearing according to claim 1, wherein the intermediate element is formed as a ring-shaped body.

3. The wheel bearing according to any claim 1, wherein the intermediate element is guided axially slidable on the axle body.

4. The wheel bearing according to claim 1, wherein the intermediate element has an engaging means at its inner circumference which is designed to engage with an engaging means on the axle body.

5. The wheel bearing according to claim 4, wherein the engaging means of the intermediate element is formed as at least a radial projection and the engaging means of the axle body is formed as at least a radial recess.

6. The wheel bearing according to claim 5, wherein the radial recess is formed as an axially extending groove.

7. The wheel bearing according to claim 1, wherein the wheel bearing has an inner bearing ring at which an outer bearing ring or a wheel hub is arranged rotatably by means of at least one bearing body.

8. The wheel bearing according to claim 7, wherein the intermediate element and the inner bearing ring of the hub assembly are connected to each other untwistably.

9. The wheel bearing according to claim 1, wherein the intermediate element is formed separately from the hub assembly.

10. The wheel bearing according to claim 7, wherein the intermediate element and the inner bearing ring of the hub assembly are formed as a single piece.

11. The wheel bearing according to claim 1, wherein the fastening element and/or the intermediate element in the area of their mutual contact surfaces have a surface design which increases friction.

12. The wheel bearing according to claim 1, wherein the fastening element is formed as a hub axle nut.

13. The wheel bearing according to claim 1, which is provided at both ends of the axle body, wherein the fastening element is fixed to the axle body on the left-hand axle side by means of a left-turning thread and on the right-hand axle side by means of a right-turning thread of the axle body.
